Collaborations, such as the Human Brain Project in Europe and the BRAIN initiative in the United States, are exploring making great advances in understanding the brain’s circuitry and computing principles.The supposed goals of these research initiatives are to understand the cause of and to improve treatment of brain disorders, to create neu [...]
After years of silence on all but the most prosaic aspects of the secretive X-37B space plane program, the Defense Department has revealed that the mysterious, truck-sized craft's next mission will host an experimental new thrust system that could greatly improve the shelf life of satellites.
The X-37B program has sent its shuttle-like Orbital Test Vehicle craft into space three times for a total time in orbit of almost four years. What the spacecraft has been doing up there is anybody's guess — its creators have declined to comment except to say that everything is working properly. But a news release this week from the Air Force says in no uncertain terms that the next flight of the X-37B, set to begin next month, will be the platform for testing a Hall thruster.
Hall thrusters combine electricity and a noble gas like xenon to produce a miniscule amount of direct force — weak in comparison with thrusters that use ordinary solid fuel, but at a far lesser cost of fuel. Trading power for fuel efficiency would allow satellites and probes to make course adjustments for much longer, extending their lives and versatility. Spaceflight Now has more details on how the system works.
Of course, this sheds no light on what the last three X-37B missions were — but in light of this new information it seems more likely that it's a test bed for high-tech space experiments, and not an orbital bomber or elite spy satellite. But you never know.
pcmag.com IBM's Watson supercomputer may be saving lives and educating children, but Google's new AI program can master video games without human guidance.
The artificial intelligence system from London-based DeepMind, which Google acquired last year for a reported $400 million, represents a major step toward a future of smart machines.
Computers running the deep Q-network (DQN) algorithm were exposed to 49 retro games on the Atari 2600 and told to play them, without any direction from researchers. Using the same network architecture and tuning parameters, the machines were given only raw screen pixels, available actions, and game score as input.
For each level passed or high score earned, the computer was automatically rewarded with a digital treat.
"Strikingly, DQN was able to work straight 'out of the box' across all these games," DeepMind's Dharshan Kumaran and Demis Hassabis wrote in a blog post. The executives cited classic titles like Breakout, River Raid, Boxing, and Enduro.
The AI crushed even the most expert humans at 29 games, sometimes composing what the creators called "surprisingly far-sighted strategies" that allowed maximum scoring possibilities. It also outperformed previous machine-learning methods in 43 of 49 instances.

Google DeepMind's findings were presented in a paper published in this week's Nature journal, which describes the key DQN features that allow it to learn.
"This work offers the first demonstration of a general purpose learning agent that can be trained end-to-end to handle a wide variety of challenging tasks," the researchers said. "This kind of technology should help us build more useful products."
Imagine asking the Google app to complete a complex task—like plan a backpacking trip through Europe, for example.
Google's DeepMind also hopes its technology will give researchers new ways to make sense of large-scale data, opening the door to discoveries in fields like climate science, physics, medicine, and genomics.
"And it may even help scientists better understand the process by which humans learn," Kumaran and Hassabis said, citing physicist Richard Feynman, who famously said, "What I cannot create, I do not understand."

IT'S been described as science fiction made real - but now, just as the final selection process gets under way for the folk with the right stuff to make a manned mission to Mars, scientists have dashed the dreams of planet Earth by warning the journey will probably never happen and will end in disaster if it does.
Privately run space exploration programme Mars One wants to send four people to the red planet for the rest of their (probably not very long) lives and film it for reality TV in order to help finance the endeavour.
Thousands have set their sights on becoming the first settlers to land on the planet - and have now been whittled down to a short list of 100, including a Scottish PhD student - but with questionable technology, a lack of funding and an unrealistic timeframe, experts claim it is a "suicide mission".
Mars One believes it can achieve a manned mission in 2024 - sooner than NASA, the European Space Agency, the Russians or Chinese, and on a fraction of their budgets.
If the project does go ahead, the crew would have to make it through nine months of interplanetary travel without being killed by mishap, radiation - or each other.
And even then, a recent study suggested they will only last 68 days on Mars before dying - due to lack of food and water.
However, Anu Ojha OBE, director of the UK National Space Academy Programme, has warned the applicants not to get their hopes up as the mission is unlikely to ever leave the ground.
Ojha said: "Obviously this is something that has captured the public's imagination, and Mars One obviously has a great PR team, but space engineering obeys the laws of physics not PR." Mars One is the brainchild of Dutch entrepreneur Bas Lansdorp who was inspired by the images of Mars sent back by the Sojourner rover in 1997, when he was a student.
Lansdorp, who will not make the journey himself, has an impressive team working on the project including former NASA employees Dr Norbert Kraft, who specialises in the physiological and psychological effects of space travel and space architect Kristian von Bengtson.
Physicist Arno Wielders, who previously worked for Dutch Space, is also on board, as well as a number of other advisers from around the world with backgrounds in space engineering, science and technology, marketing, design and television production.
The ultimate aim is to see a large, self-sustaining colony on Mars, but Ojha, who is also a director at the National Space Centre in Leicester, said there are three major stumbling blocks for the mission: technology, funding and human psychology.
"In terms of technology, it's pushing the absolute boundaries and there seems to be a lot of technological naivety on the part of the people running it", he said.
"There are some elements that seem reasonable, but overall it's concerning, and the timescales are also questionable."
While Mars One is planning the one way mission for 2024, NASA, with its long established expertise and technology, is looking to be able to send humans to Mars and bring them back again by the mid 2030s.
This is estimated to cost up to as much as £100 billion (£64.9bn) for the space agency, while Mars One believes it can do it for an optimistic $6 billion (£3.9bn) - and there are even questions over whether or not they will be able to achieve that much funding. The private enterprise is hoping to raise money through a TV deal and additional funding from the exposure that will bring the project.
Last year it said it had teamed up with programme makers Endemol, but the Big Brother creators recently pulled out of the deal claiming they were "unable to reach agreement on the details of the contract".
Mars One did not respond to questioning by the Sunday Herald over its funding, but its website showed that as at January this year, it had raised just $759,816 from donations, merchandising, and a crowdfunding campaign.
It is unclear what other funding the project has.
Ojha said: "The business model has so many holes in it, it's shaky to say the least. And when you ask them how much money they have raised, they say it's still ongoing. The time scales and the business model - they're completely unrealistic."
Mars One plans to send several unmanned rockets to Mars ahead of the 2024 mission, with the first of these scheduled to take place in 2018.
These will include missions with robots to find a suitable location for a base and assemble it ahead of the humans' arrival. The project claims it will use only existing technology for the mission, buying in materials from proven suppliers including Lockheed Martin or SpaceX.
The equipment involved includes several simulation outposts for training, a rocket launcher, a transit vehicle to take the crew to Mars, a Mars landing capsule, two rovers, a Mars suit and a communications system.
However, experts have warned that much of this equipment has not been fully tested.
Physicist professor Todd Huffman is a big supporter of attempting a manned mission to Mars, but he also has serious concerns about Mars One, claiming it is "scientifically irresponsible".
He said: "The plan stretches the technology in many places. "The launch vehicle they want to use has not actually ever launched yet, let alone make a trip to Mars.
"The living spaces have not been made nor has it been tested whether they can be robotically assembled and by what kind of robot.
"A suitable site would also need to be found for the living spaces and the details of how water extraction will take place have not been understood.
"If you assign a 90 per cent chance to success to each of those things, all of which are necessary for human survival, you end up with about a 50 per cent chance of failure, ending in the death of the colonists - and that would likely not make good television." He added: "Unless we [wait for] quite a lot of technology and exploration to happen first, it is basically worse than a one-way ticket for the colonists - it is almost surely a suicide mission if carried out within this next decade."
Although most scientists believe the mission will not go ahead, some have also warned of the psychological impact on the people selected for the mission if it does.
Ojha said: "The thing that's really captured the public's imagination is this idea of it being a one way trip, but this brings another set of problems in terms of human psychology.
"The longest period a human has spent in space is 438 days - they're talking about sending people on a one way trip. "Lots of the people I've seen interviewed, they're really excited about taking part, but have they really thought about what they're doing and what the implications are?
"I would tell them to go to Antarctica for six months in the middle of winter and that's about 1 per cent of what they'll be experiencing on Mars.
"Human psychology is far more fragile than we think."
However, while many scientists warn of the dangers and do not believe the mission will proceed, they have praised Mars One for sparking the public's interest in planetary science.
Dr John Bridges, of the Space Research Centre in Leicester, said: "It's a very interesting and innovative project, but the time scales are very challenging.
"I believe they're planning for 2024 and it's 2015 now. So for something as major as this, it's a very challenging timescale "But it's fantastic that people are thinking about this, that industry is getting involved and raising awareness of planetary science."
Ojha added: "Mars One has been great in a way because it's once again drawn people's imagination to the idea of space engineering and exploration.
"But the reality is that there are serious concerns about the project's space engineering, funding and medical implications."
Lansdorp has previously said that most people are "surprised to hear that the manned missions will be happening in ten years time, with a budget ten times less than Nasa".
He added: "But I think that if you really spend time studying Mars One, you cannot believe there is not a good chance we will make it. "At the same time, it's a hugely ambitious plan, there's many things that can go wrong with such a big plan.
"But I believe we have a good plan and we can overcome the challenges."
However, he has also conceded that the current plans are an "optimum schedule", adding: "If one rocket doesn't launch, or a lander doesn't work on Mars before a human goes, any major malfunctions will result in a two year delay."
Mars One declined the Sunday Herald's request to interview someone from the project and failed to answer any of our questions.
The »unknown benefactor« has assisted in funding a few projects and good things have been done. Navajo elders have received heating generators to survive harsh winter and a certain non-profit organization has received funds which would help constructing a greenhouse dome which will grow free food for the hungry.
Many project proposals have been received, but only about 10% of them can really improve the timeline for this planet. However, many good projects exist and some of them are presented on this website:
It is time now to widen our horizons.There are good projects out there that can really change the future of this planet. We need to go beyond the old cliche where all the good guys are poor and all the bad guys have the money. There are tens of thousands people reading this blog daily, and according to statistics, about a hundredof them are millionaires and one of them has tens of millions:
Humanity may have already created its own nemesis, Professor Stephen Hawking warned last week. The Cambridge University physicist claimed that new developments in the field of artificial intelligence (AI) mean that within a few decades, computers thousands of times more powerful than in existence today may decide to usurp their creators and effectively end humanity’s 100,000-year dominance of Earth. This Terminator scenario is taken seriously by many scientists and technologists. Before Prof. Hawking made his remarks, Elon Musk, the genius behind the Tesla electric car and PayPal, had stated that “with artificial intelligence, we are summoning the demon,” comparing it unfavourably with nuclear war as the most potent threat to humanity’s existence. Aside from the rise of the machines, many potential threats have been identified to our species, our civilization, even our planet. To keep you awake at night, here are seven of the most plausible.

1. ASTEROID STRIKE Our solar system is littered with billions of pieces of debris, from the size of large boulders to objects hundreds of kilometres across. We know that, from time to time, these hit the Earth. Sixty-five-million years ago, an object – possibly a comet a few times larger than the one on which the Philae probe landed last month – hit the Mexican coast and triggered a global winter that wiped out the dinosaurs. In 1908, a smaller object hit a remote part of Siberia and devastated hundreds of square kilometres of forest. Last week, 100 scientists, including Lord Rees of Ludlow, the Astronomer Royal, called for the creation of a global warning system to alert us if a killer rock is on the way. Probability: remote in our lifetime, but one day we will be hit. Result: there has been no strike big enough to wipe out all life on Earth – an “extinction-level event” – for at least three billion years. But a dino-killer would certainly be the end of our civilization and possibly our species.
Warner Bros.When artificial intelligence becomes self-aware, there is a chance it will look something like this scene from Terminator 3.
2. ARTIFICIAL INTELLIGENCE Prof. Hawking is not worried about armies of autonomous drones taking over the world, but something more subtle – and more sinister. Some technologists believe that an event they call the Singularity is only a few decades away. This is a point at which the combined networked computing power of the world’s AI systems begins a massive, runaway increase in capability – an explosion in machine intelligence. By then, we will probably have handed over control to most of our vital systems, from food distribution networks to power plants, sewage and water treatment works, and the global banking system. The machines could bring us to our knees without a shot being fired. And we cannot simply pull the plug, because they control the power supplies.
Probability: unknown, although computing power is doubling every 18 months. We do not know if machines can be conscious or “want” to do anything, and sceptics point out that the cleverest computers in existence are currently no brighter than cockroaches. Result: if the web wakes up and wants to sweep us aside, we may have a fight on our hands (perhaps even something similar to the man vs. machines battle in the Terminator films). But it is unlikely that the machines will want to destroy the planet – they “live” here, too.

3. A GENETICALLY CREATED PLAGUE This is possibly the most terrifying short-term threat because it is so plausible. The reason Ebola has not become a worldwide plague – and will not do so – is because it is so hard to transmit, and because it incapacitates and kills its victims so quickly. However, a modified version of the disease that can be transmitted through the air, or which allows its host to travel around for weeks, symptom-free, could kill many millions. It is unknown whether any terror group has the knowledge or facilities to do something like this, but it is chilling to realize that the main reason we understand Ebola so well is that its potential to be weaponized was quickly realized by defence experts. Probability: someone will probably try it one day. Result: potentially catastrophic. “Ordinary” infectious diseases such as avian-flu strains have the capability to wipe out hundreds of millions of people.

4. NUCLEAR WAR This is still the most plausible “doomsday” scenario. Despite arms-limitations treaties, there are more than 15,000 nuclear warheads and bombs in existence – many more, in theory, than would be required to kill every human on Earth. Even a small nuclear war has the potential to cause widespread devastation. In 2011, a study by NASA scientists concluded that a limited atomic war between India and Pakistan involving just 100 Hiroshima-sized detonations would throw enough dust into the air to cause temperatures to drop more than 1.2C globally for a decade. Probability: high. Nine states have nuclear weapons, and more want to join the club. The nuclear wannabes are not paragons of democracy. Result: it is unlikely that even a global nuclear war between Russia and NATO would wipe us all out, but it would kill billions and wreck the world economy for a century. A regional war, we now know, could have effects far beyond the borders of the conflict.
CERN)/MCTThis is one of the huge particle detectors in the Large Hadron Collider, a 17 mile-long tunnel under the French-Swiss border. Scientists are searching for evidence of what happened right after- and perhaps before- the Big Bang.
5. PARTICLE ACCELERATOR DISASTER Before the Large Hadron Collider (LHC), the massive machine at CERN in Switzerland that detected the Higgs boson a couple of years ago, was switched on, there was a legal challenge from a German scientist called Otto Rossler, who claimed the atom-smasher could theoretically create a small black hole by mistake – which would then go on to eat the Earth. The claim was absurd: the collisions in the LHC are far less energetic than those caused naturally by cosmic rays hitting the planet. But it is possible that, one day, a souped-up version of the LHC could create something that destroys the Earth – or even the universe – at the speed of light. Probability: very low indeed. Result: potentially devastating, but don’t bother cancelling the house insurance just yet.

6. ‘GOD’ REACHES FOR THE OFF-SWITCH Many scientists have pointed out that there is something fishy about our universe. The physical constants – the numbers governing the fundamental forces and masses of nature – seem fine-tuned to allow life of some form to exist. The great physicist Sir Fred Hoyle once wondered if the universe might be a “put-up job”. More recently, the Oxford University philosopher Nick Bostrom has speculated that our universe may be one of countless “simulations” running in some alien computer, much like a computer game. If so, we have to hope that the beings behind our fake universe are benign – and do not reach for the off-button should we start misbehaving. Probability: according to Professor Bostrom’s calculations, if certain assumptions are made, there is a greater than 50% chance that our universe is not real. And the increasingly puzzling absence of any evidence of alien life may be indirect evidence that the universe is not what it seems. Result: catastrophic, if the gamers turn against us. The only consolation is the knowledge that there is absolutely nothing we can do about it.

Global warming is rapidly turning America the beautiful into America the stormy and dangerous, according to the National Climate Assessment report released Tuesday, May 6, 2014.
7. CLIMATE CATASTROPHE Almost no serious scientists now doubt that human carbon emissions are having an effect on the planet’s climate. The latest report by the Intergovernmental Panel on Climate Change suggested that containing temperature rises to below 2C above the pre-industrial average is now unlikely, and that we face a future three or four degrees warmer than today. This will not literally be the end of the world – but humanity will need all the resources at its disposal to cope with such a dramatic shift. Unfortunately, the effects of climate change will really start to kick in just at the point when the human population is expected to peak – at about nine billion by the middle of this century. Millions of people, mostly poor, face losing their homes to sea-level rises (by up to a metre or more by 2100) and shifting weather patterns may disrupt agriculture dramatically. Probability: it is now almost certain that CO2 levels will keep rising to 600 parts per billion and beyond. It is equally certain that the climate will respond accordingly. Result: catastrophic in some places, less so in others (including northern Europe, where temperature rises will be moderated by the Atlantic). The good news is that, unlike with most of the disasters here, we have a chance to do something about climate change now.
As the planet continues to raise her vibration toward a fifth dimensional frequency, the ability to manifest is becoming easier and faster. Ultimately those who are awakened to the possibility of a New Earth are working toward manifesting this into reality and need to know the missing piece of manifestation in order to be successful co-creators. The trinity of manifestation Manifestation involves using heartfelt intention, the Law of Attraction, and the Universal Law of Detachment. T [...]
